Glucosamine
Glucosamine is a substance that naturally occurs in cartilage. Cartilage is basically the connective tissue in your body, one of its roles is to protect the ends of bones, especially in the joints. As we age, and for those with osteoarthritis, that connective tissue begins to wear down, causing pain and ache. Glucosamine is said to act as an anti-inflammatory and may help to slow the deterioration of cartilage.
